Description

Technical Field

[0001] The present invention relates to the technical field of raw material extraction, and more particularly to a device for extracting and preparing hemp active peptide raw materials. Background Art

[0002] The device for extracting and preparing hemp active peptide raw materials is a set of devices specifically designed to efficiently and safely extract and prepare active peptides from hemp plants. This set of devices usually includes key parts such as a crushing system, an extraction system, a separation and purification system, and a subsequent treatment system, aiming to ensure that the purity and activity of the final product - hemp active peptide reach the expected standards through a series of precisely controlled process steps. In order to release the active peptides from hemp, it is first necessary to perform a crushing treatment on it. The crushing system can be equipped with efficient crushing rollers or grinding mechanisms, which can finely crush the hemp while maintaining the high activity of the hemp oligopeptides. For example, the Chinese invention patent with the publication number CN116571323A discloses a device for extracting plant raw materials for preparing lip balm. Multiple crushing cutters perform cutting and crushing treatment on the plant raw materials, and the crushed plant raw materials are conveyed to the pressing cylinder through a screw conveyor. The crushed plant raw materials are mutually extruded in the pressing cylinder, thereby realizing the pressing of the crushed plant raw materials. Such a device is suitable for the processing of hemp active peptide raw materials.

[0003] However, relying solely on the mutual extrusion force between the crushed raw materials in the pressing cylinder to achieve the pressing of the raw materials, this pressing method has low extraction efficiency of the original liquid, poor pressing effect, and low raw material utilization rate.

[0004] Therefore, the present invention proposes a device for extracting and preparing hemp active peptide raw materials to achieve efficient pressing treatment of the crushed materials while continuously and stably crushing the raw materials, and improve the utilization rate and extraction efficiency of the raw materials. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for extracting and preparing hemp active peptide raw materials to solve the problem of how to achieve efficient pressing treatment of the crushed materials while continuously and stably crushing the raw materials, and improve the utilization rate and extraction efficiency of the raw materials as described in the above background art.

[0006] The present invention provides the following technical solution: An extraction and preparation device for hemp active peptide raw materials, including a preparation box. Inside the preparation box, there are a crushing chamber, a material distribution chamber, and a liquid collection chamber from top to bottom in sequence. A screening member that separates the two is assembled between the crushing chamber and the material distribution chamber. A crushing component, a flow control component, and a stamping table are respectively arranged in the crushing chamber, the material distribution chamber, and the liquid collection chamber. The crushing component, the flow control component, and the stamping table are assembled on the surface of a transmission shaft vertically established at the center of the preparation box. A retracting and releasing component connected to the stamping table is arranged at the bottom of the liquid collection chamber. A displacement detection part for detecting the moving state of the stamping table is arranged on the side wall of the liquid collection chamber. A driving component connected to the transmission shaft is assembled above the preparation box, and a controller is assembled on the outer wall of the preparation box;

[0007] The transmission shaft is successively an assembly section, a threaded section, and a strip section from top to bottom. The assembly section, the threaded section, and the strip section are respectively located in the crushing chamber, the material distribution chamber, and the liquid collection chamber;

[0008] The flow control component includes a lifting table, a telescopic rod, a traction seat, and a connecting rod. Among them, the lifting table is slidably arranged on the strip section of the transmission shaft. A telescopic rod connected to a sieve plate is arranged at the top of the lifting table. The bottom end of the lifting table is rotatably clamped with a traction seat, and the bottom of the traction seat is fixedly connected to the stamping table through a connecting rod. The retracting and releasing component includes two groups of scraping plates distributed left and right, a rotating shaft seat, and a swinging rod. The left and right scraping plates are slidably arranged on the bottom wall of the liquid collection chamber. Rotating shaft seats are installed at the front and rear ends inside the two scraping plates. The two swinging rods are distributed in a front-back cross shape. The top ends of the two swinging rods are rotatably connected to the same connecting shaft, and the bottom ends of the two swinging rods are respectively rotatably connected to the corresponding rotating shaft seats. The connecting shaft is installed on the front and rear side walls of the stamping table.

[0009] Further, the crushing component includes a crushing wheel, a shaft sleeve, and a first positioning frame. Among them, the shaft sleeve is fixedly assembled on the assembly section of the transmission shaft. A crushing wheel is installed on the periphery of the shaft sleeve. The crushing wheel is designed with a double-sided blade in a laminated structure. The shaft sleeve is rotatably arranged in the rotating shaft groove of the first positioning frame. The inner wall surface of the crushing chamber is provided with circumferentially distributed blocking blades, which cooperate with the crushing wheel to form an inner and outer multi-layer crushing space.

[0010] Further, an insertion cavity is arranged in the middle of the stamping table. The top wall of the insertion cavity is in a spiral engagement with the threaded section of the transmission shaft, and sliding grooves that can move up and down along the guiding sliding plates on the inner wall of the preparation box are arranged on the left and right side walls of the stamping table.

[0011] Further, the displacement detection part includes a generator and a displacement sensor. Among them, the generator is installed on the side wall of the stamping table, and the displacement sensor is installed on the inner wall of the preparation box on the same side as the generator.

[0012] Further, a guiding groove that can fit with the bottom of the lifting table is arranged between the material distribution chamber and the liquid collection chamber.

[0013] Further, the screening member includes a sieve plate and a limiting groove, wherein the limiting groove is fixedly installed on the inner wall of the preparation box, the sieve plate is rotatably arranged in the limiting groove, and the sieve plate is assembled on the transmission shaft through a bearing. The surface of the sieve plate is provided with sieve holes through which the crushed raw materials can pass.

[0014] Further, an elastic interlayer is connected between the scraping plate and the inner wall of the preparation box, and the top wall of the elastic interlayer is provided with an inclined slope towards the inside.

[0015] Further, the driving assembly includes a reversible motor, a second positioning frame and a coupling. The reversible motor can be assembled above the coupling through a machine base. The second positioning frame is installed on the outer top wall of the preparation box. The output shaft of the reversible motor is fixedly connected to the transmission shaft through the coupling. The coupling is rotatably arranged in the second positioning frame, and the output shaft of the reversible motor shows a positive and reverse equal-stroke alternating transmission.

[0016] Further, valves and hatches are respectively assembled on the front and rear side walls of the liquid collection cavity, and the hatch is detachably installed on the side wall of the preparation box.

[0017] Further, a hopper is installed on the top wall of the preparation box below the driving assembly, and the hopper is communicated with the crushing cavity.

[0018] The technical effects and advantages of the present invention:

[0019] Through the coordinated use of the flow control component, the stamping table and the retracting and releasing component, the present invention is conducive to the positive and reverse equal-stroke alternating transmission of the transmission shaft, and both can carry the crushing wheel pair to crush the hemp active peptide raw materials entering the crushing cavity. When entering the positive rotation stage, the stamping table moves upward. On the one hand, the stamping table can carry the traction seat and the lifting table rotatably arranged above it to lift through the connecting rod, so that the lifting table gradually moves upward away from the material guiding groove, expanding the discharge space at the bottom of the material distribution cavity. On the other hand, the stamping table can also carry the connecting shaft to rise together, so that the two swing rods distributed in a crosswise and staggered manner on the same side deflect and converge inward with the connecting shaft as the center. Then, the bottom end of the swing rod can pull the scraping plates on the left and right sides to approach each other inward through the rotating shaft seat, so that the new falling materials or the raw materials after the previous round of pressing can be pushed by the scraping plates and accumulate towards the middle. During this period, the output power of the reversible motor increases, and the lifting table sliding on the key section of the transmission shaft rotates coaxially during the upward movement. Then, the lifting table can carry the sieve plate to rotate synchronously through the telescopic rod. In this way, the increase in torque force will bring an increase in the rotation speed of the sieve plate, accelerating the centrifugal separation speed of the crushed materials in the crushing cavity, that is, entering the material distribution cycle. On the contrary, when the transmission shaft enters the reverse rotation stage, the stamping table, the retracting and releasing component, the flow control component and the screening member will perform the transmission process opposite to the above, entering the pressing cycle.

Detailed implementation manners

[0031] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are merely examples, and an apparatus for extracting and preparing a hemp active peptide raw material according to the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0032] Referring to Figures 1 - 10 , the present invention provides an apparatus for extracting and preparing a hemp active peptide raw material, including a preparation tank 1. Inside the preparation tank 1, there are a crushing chamber, a material distribution chamber, and a liquid collection chamber from top to bottom in sequence. A screening member 6 that separates the two is assembled between the crushing chamber and the material distribution chamber. A crushing assembly 2, a flow control assembly 3, and a punching table 4 are respectively arranged in the crushing chamber, the material distribution chamber, and the liquid collection chamber. The crushing assembly 2, the flow control assembly 3, and the punching table 4 are assembled on the surface of a transmission shaft 7 vertically established at the center of the preparation tank 1. A retracting and releasing assembly 5 connected to the punching table 4 is arranged at the bottom of the liquid collection chamber. A displacement detection portion 8 for detecting the moving state of the punching table 4 is arranged on the side wall of the liquid collection chamber. Above the preparation tank 1, a driving assembly 9 connected to the transmission shaft 7 is assembled, and a controller 10 is assembled on the outer wall of the preparation tank 1.

[0033] In this embodiment, it should be specifically noted that the transmission shaft 7 is successively an assembly section, a threaded section, and a card strip section from top to bottom. The assembly section, the threaded section, and the card strip section are respectively located in the crushing chamber, the material distribution chamber, and the liquid collection chamber, and are used to drive the crushing assembly 2, the flow control assembly 3, and the punching table 4 to operate respectively, so as to perform corresponding crushing operations, material distribution operations, and pressing operations.

[0034] The controller 10 can receive the determination information output by the displacement sensor 802, and output a control instruction for the actuator through analysis and processing;

[0035] A hopper is installed on the top wall of the preparation tank 1 and is located below the driving assembly 9. The hopper is communicated with the crushing chamber, so that the hemp active peptide raw material can be injected into the crushing chamber from the hopper, which is convenient for the feeding operation;

[0036] Valves 11 and hatches 12 are respectively assembled on the front and rear side walls of the liquid collection chamber. Among them, the hatch 12 is detachably installed on the side wall of the preparation tank 1. The discharge of the original liquid in the liquid collection chamber can be regulated by opening and closing the valve core of the valve 11. Similarly, the waste residue after pressing treatment in the liquid collection chamber can be taken out by opening the hatch 12;

[0037] The driving assembly 9 includes a reversible motor 901, a second positioning bracket 902 and a coupling 903. The reversible motor 901 can be assembled above the coupling 903 through a machine base. The second positioning bracket 902 is installed on the outer top wall of the preparation box 1. The output shaft of the reversible motor 901 is fixedly connected to the transmission shaft 7 through the coupling 903. The coupling 903 is rotatably arranged in the second positioning bracket 902, so that the reversible motor 901 can stably output, and its output shaft shows positive and reverse equal-stroke alternating transmission. During this process, the output shaft of the reversible motor 901 can drive the transmission shaft 7 assembled therewith to rotate coaxially through the coupling 903, so that the transmission shaft 7 has the property of positive and reverse self-rotation. The positive and reverse equal-stroke alternating transmission means that during the forward and reverse transmission processes of the output shaft, its transmission path or stroke is equal in length or symmetric to a certain extent.

[0038] In this article, all the positional relationships regarding front, back, left, and right discussed are defined based on Figures 1 - 3 the presented perspective. These azimuth descriptions do not have actual geographical or physical meanings. They are merely a reference framework set to help readers more intuitively understand the content in the article. In this way, we can more clearly show the relative positional relationships between various parts, making the entire discussion process easier to understand and follow. Please note that this custom azimuth identification is only applicable for internal use in this article and does not represent any absolute direction or position in the real world.

[0039] Referring to Figure 2 and Figures 5 - 6 the crushing assembly 2 includes a crushing wheel 201, a bushing 202 and a first positioning bracket 203. The bushing 202 is fixedly assembled on the assembly section of the transmission shaft 7. A plurality of crushing wheels 201 are installed on the periphery of the bushing 202 from top to bottom. The crushing wheels 201 are of a laminated design with double-sided blades, that is, formed by overlapping crushing blades arranged in two opposite directions. The bushing 202 is rotatably arranged in the rotating shaft groove in the middle of the first positioning bracket 203, playing a further limiting role and improving the stability when the transmission shaft 7 drives the crushing assembly 2 to operate, ensuring the stable output of the transmission shaft 7 in the vertical direction.

[0040] In this embodiment, it should be specifically noted that the inner wall surface of the crushing cavity is provided with circumferentially distributed blocking blades, which cooperate with the crushing wheels 201 to form an inner and outer multi-layer crushing space, so as to increase the crushing surface of the hemp active peptide raw material in the crushing cavity, increase the crushing resistance, and improve the crushing efficiency and effect.

[0041] Referring to Figures 4 - 10, the flow control component 3 includes a lifting platform 301, a telescopic rod 302, a traction seat 303 and a connecting rod 304. The lifting platform 301 is slidably arranged on the strip section of the transmission shaft 7. The top of the lifting platform 301 is provided with a telescopic rod 302 that can be connected to the sieve plate 601. The bottom end of the lifting platform 301 is rotatably clamped with a traction seat 303. The bottom of the traction seat 303 is fixedly connected to the stamping platform 4 through the connecting rod 304. On the one hand, the stamping platform 4 can drive the traction seat 303 and the lifting platform 301 rotatably arranged above it to move up and down through the connecting rod 304, so that the lifting platform 301 moves upward away from or downward close to the material guiding groove, adjusting the discharging space of the material distribution cavity. On the other hand, the lifting platform 301 slidably arranged on the strip section of the transmission shaft 7 rotates coaxially during the upward movement, and then the lifting platform 301 can drive the sieve plate 601 to rotate synchronously through the telescopic rod 302, separating the crushed raw materials by centrifugal force;

[0042] The winding and unwinding component 5 includes two groups of scraping plates 501 distributed left and right, a rotating shaft seat 502 and a swing rod 503. The left and right scraping plates 501 are slidably arranged on the bottom wall of the liquid collecting cavity. The front and rear ends of the inner sides of the two scraping plates 501 are both provided with rotating shaft seats 502. The two swing rods 503 are distributed in a front and rear cross pattern. The tops of the two swing rods 503 are rotatably connected to the same connecting shaft 504. The bottoms of the two swing rods 503 are respectively rotatably connected to the corresponding rotating shaft seats 502. The front and rear side walls of the stamping platform 4 are provided with connecting shafts 504. When the stamping platform 4 drives the connecting shaft 504 to rise together, the two swing rods 503 distributed in a cross and staggered manner on the same side deflect and converge inward with the connecting shaft 504 as the center. The bottom end of the swing rod 503 can drive the scraping plates 501 on the left and right sides to approach each other inward through the rotating shaft seat 502, so that the new falling materials or the raw materials after the previous round of pressing can be pushed by the scraping plates 501 and piled up in the middle, creating conditions for the next round of pressing operation of the stamping platform 4, ensuring that the piled materials can be fully pressed in each cycle, and improving the pressing efficiency and effect.

[0043] In this embodiment, it should be specifically noted that the screening member 6 includes a sieve plate 601 and a limiting groove 602. The limiting groove 602 is fixedly installed on the inner wall of the preparation box 1. The sieve plate 601 is rotatably arranged in the limiting groove 602, and the sieve plate 601 can be assembled on the transmission shaft 7 through a bearing. The surface of the sieve plate 601 is provided with sieve holes through which the crushed raw materials can pass;

[0044] A material guiding groove that can fit with the bottom of the lifting platform 301 is arranged between the material distribution cavity and the liquid collecting cavity, and its opening degree determines the rate at which the crushed raw materials enter the liquid collecting cavity from the material distribution cavity;

[0045] In the middle of the stamping table 4, there is an insertion cavity. The top wall of the insertion cavity is in spiral engagement with the threaded section of the transmission shaft 7. Moreover, sliding grooves are provided on the left and right side walls of the stamping table 4, which can move up and down along the guiding sliding plates on the inner wall of the preparation box 1. When the transmission shaft 7 rotates forward or reversely, the stamping table 4 can move up and down along the threaded section of the transmission shaft 7 under the limitation of the guiding sliding plates on the inner wall of the preparation box 1.

[0046] The displacement detection unit 8 includes a generator 801 and a displacement sensor 802. Among them, the generator 801 is installed on the side wall of the stamping table 4, and the displacement sensor 802 is installed on the inner wall of the preparation box 1 on the same side as the generator 801, preferably above the liquid collection cavity. The displacement sensor 802 can detect the moving position of the generator 801 to determine the change in the distance between the generator 801 and the displacement sensor 802. When the generator 801 rises together with the stamping table 4, the generator 801 gradually approaches the displacement sensor 802, and the distance between the two decreases, and the distance change is determined to be a negative change, and vice versa for a positive change.

[0047] An elastic partition layer 505 is connected between the scraping plate 501 and the inner wall of the preparation box 1, and the top wall of the elastic partition layer 505 is provided with an inclined slope towards the inside. The elastic partition layer 505 can elastically expand and contract with the scraping plate 501 to block the falling material and prevent the falling material from entering between the scraping plate 501 and the inner wall of the preparation box 1.

[0048] The working principle of the present invention:

[0049] When the equipment is started, the reversible motor 901 is started, and its output shaft shows positive and reverse equal-stroke alternating transmission. During this period, the output shaft of the reversible motor 901 can drive the coaxial rotation of the transmission shaft 7 assembled with it through the coupling 903, so that the transmission shaft 7 has the property of positive and reverse self-rotation. Combined with the laminated design of the double-sided blades of the crushing wheel 201, no matter which direction the transmission shaft 7 rotates, it can perform efficient and stable crushing operations on the hemp active peptide raw materials entering the crushing cavity. The crushed raw materials are blocked above the screening member 6, and only when the particle size of the crushed material is smaller than the inner diameter of the sieve holes of the sieve plate 601 can it pass through the sieve holes, and the crushed raw materials will generate the original liquid and flow to the liquid collection cavity.

[0050] At the same time, when the transmission shaft 7 enters the forward rotation stage, the punching table 4 can be lifted from bottom to top along the threaded section of the transmission shaft 7 under the limit of the guide slide plate on the inner wall of the preparation box 1, and gradually move away from the bottom wall of the liquid collecting chamber. On the one hand, the punching table 4 can carry the traction seat 303 and the lifting platform 301 rotatably arranged above it through the connecting rod 304 to lift it, so that the lifting platform 301 gradually separates from the material guide groove upward, expanding the discharge space at the bottom of the material distribution chamber. On the other hand, the punching table 4 can also carry the connecting shaft 504 to rise together, so that the two swing rods 503 staggered on the same side are deflected inward with the connecting shaft 504 as the center. The bottom end of the swing rod 503 can pull the scrapers 501 on the left and right sides to move closer to the inside through the rotating shaft seat 502, so that the new blanks or the raw materials after the previous round of pressure can be pushed by the scrapers 501 and piled up in the middle, creating conditions for the next round of pressing operation of the punching table 4, ensuring that the pile can be fully pressed in each cycle, improving the pressing efficiency and pressing effect, and the elastic interlayer 505 can elastically expand and contract with the scrapers 501 to block the blanks and prevent the blanks from entering between the scrapers 501 and the inner wall of the preparation box 1, ensuring the normal operation of the equipment and further improving the utilization rate of the blanks;

[0051] During this time, the displacement sensor 802 can detect the moving position of the generator 801 to determine the change in the distance between the generator 801 and the displacement sensor 802. When the generator 801 rises together with the punching table 4, the generator 801 gradually approaches the displacement sensor 802, and the distance between the two decreases. It is determined that the distance change is a negative change, and the displacement sensor 802 outputs negative change information to the controller 10. The controller 10 receives the negative change information and outputs a control instruction to the reversible motor 901, and controls the output power of the reversible motor 901 to increase, which can be increased by 1 times to increase the torque of the transmission shaft 7. The lifting platform 301 slidably arranged on the card section of the transmission shaft 7 rotates coaxially therewith during the upward movement, and then the lifting platform 301 can carry the screen plate 601 to rotate synchronously through the telescopic rod 302. In this way, the increase in torque will bring about an increase in the rotation speed of the screen plate 601, and accelerate the speed of centrifugal separation of the crushed material in the crushing chamber, that is, enter the material separation cycle;

[0052] On the contrary, when the transmission shaft 7 enters the reverse rotation stage, the punching table 4, the retracting assembly 5, the flow control assembly 3 and the screening element 6 will implement the opposite transmission process to the above, wherein the punching table 4 moves downward, and at the same time pushes the retracting assembly 5 to open to both sides to compress the pile, during which the lifting platform 301 gradually moves downward and approaches the guide trough, and at the same time the output power of the reversible motor 901 decreases, the rotation speed of the screen plate 601 decreases, and the discharge speed slows down, that is, entering the pressing cycle;

[0053] By means of the positive and reverse equal-range alternating transmission operation of the transmission shaft 7, the raw materials can be continuously and stably crushed while the crushed materials can be efficiently squeezed, thereby improving the utilization rate of the raw materials and the extraction efficiency.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention; making equivalent substitutions or modifications according to the technical scheme of the present invention and its improvement conceptions should all be included under the protection of the present invention.
